In the collaboration with Institute of Chemical Technology and Analytics (TU Wien) we ran the project on collecting both elemental and molecular information from the very same slice! The methods employed – µXRF for elemental and MALDI for molecular information. The sample on which we tested the workflow could be easily bought on market – chicken feet (phalanx section was measured). Yummy!
The project is described in the paper “Multimodal imaging of undecalcified tissue sections by MALDI MS and μXRF” published by Analyst.
The Seminar Activation Analysis and Gamma Spectroscopy (SAAGAS 26), took place on 19-22 February in TU Wien, Vienna, Austria. Our group from Atominstitut contributed to the Seminar 2 oral presentations, as well as 5 posters – and three of the posters were devoted to biological samples:
- Total X-ray reflection spectrometry of black tea and herbal infusions
- μXRF spectrometer of Atominstitut in bio-imaging application
- Confocal μXRF spectrometer for low to high Z element analysis
We’re very delighted to share, that the talk of Mirjam Rauwolf – “Synchrotron radiation micro XRF analysis of zinc in osteosarcoma tissue” received an award!
The paper “Atomic layer deposition to prevent metal transfer from implants: an X-Ray Fluorescence study” (doi: 10.1016/j.apsusc.2015.09.248, available online since 3 October 2015) is the result of collaboration with University of Brescia (Dr. Fabjola Bilo, Dr. Laura Borgese and Prof. Laura E. Depero). Micro-X-ray fluorescence analysis was performed on micro-XRF spectrometer at Atominstitut.
